Featured image for .NET

.NET 6 is now generally available on Red Hat Enterprise Linux (RHEL) 7, RHEL 8, and Red Hat OpenShift. Here's a quick overview of what developers need to know about this new major release.

New features in .NET 6

In addition to x64 architecture (64-bit Intel/AMD), .NET is now also available for ARM64 (64-bit ARM), and s390x (64-bit IBM Z) architectures.

.NET 6 includes new language versions C# 10 and F# 6.

ASP.NET Core adds a new minimal API that leverages new C# 10 features to write web applications with less code.

Like previous versions, .NET 6 brings many performance improvements to the base libraries, GC and JIT.

.NET 6 introduces source generators for logging and JSON. Thanks to these generators, JSON serialization and logging can be performed with less allocation and better performance.

How to install .NET 6

You can install .NET 6 on RHEL 7 (x64 only) with the usual command:

# yum install rh-dotnet60

On RHEL 8 (for x64, arm64, and s390x), enter:

# dnf install dotnet-sdk-6.0

The .NET 6 SDK and runtime container images are available from the Red Hat Container Registry. You can use the container images as standalone images and with OpenShift on all supported architectures:

$ podman run --rm registry.redhat.io/ubi8/dotnet-60 dotnet --version

6.0.100
